WinZEC proving key

First time install of latest version of WinZEC on Windows 7 machine.

When I launch it, it starts by downloading proving key. After a few minutes I get a connection reset error and it closes.

I’ve tried “c:\Program Files\winzec\app\zcashd.exe” -damemon=0 -showmetrics=1

It starts validating transactions, but when I launch WinZEC again, I get the same error.

Any ideas?
